Silent movies in Flash!

I posted this message in my opening post and having come back to the forum I now realise that it probably should have gone here - so here it is.

I have created an sfw file from some screen recording sotftware which I am trying out (Autoscreen 2.1 pro). The problem is that when I create an sfw file from it and import it to the stage in flash and add a button to tell the movie to start, I get a silent movie when I export it! Even though the Autoscreen movie works in a flash player, I still end up with no sound from the modified Flash movie. Any Ideas anyone?

Jocke.
